AB  - This study evaluated the equilibrium, kinetics, and thermodynamics of vanadium sorption from aqueous solution onto nanocomposite functionalized with diethylene triamine in batch conditions. The effects of temperature, solution pH, and initial concentration of vanadium were examined. The maximum sorption capacity of vanadium on the tested sorbent was achieved at pH 6. The sorption capacity increased with increasing temperature and initial concentration. The equilibrium adsorption data were analyzed using Langmuir, Freundlich, Temkin, Jovanovic, Toth, Sips, Khan, and Redlich-Peterson isotherm models. The kinetics data were studied using pseudo-first-order, pseudo-second-order, the fractional power, Elovich, and Avrami models. A non-linear fitting method was used to compare the best fitting of the equilibrium and kinetic data. The sorption equilibrium data were best represented by the Langmuir, Khan, Toth, and Redlich–Peterson isotherms. The adsorption kinetics was estimated to follow the pseudo-second-order kinetic model. The mechanism of vanadium sorption was analyzed with intra-particle, Bangham, Boyd, and liquid film diffusion models. It was observed that the sorption process was controlled by the film-diffusion as well as the pore-diffusion. Thermodynamic parameters (change of standard enthalpy (ΔH°), standard entropy (ΔS°), and standard free energy (ΔG°)) suggested that the sorption of vanadium onto functionalized nanocomposite was a spontaneous and endothermic process.

AB  - The contamination of water with chromium is a global issue that is especially severe in developing countries with intensive mining and heavy industry (South Africa, Pakistan, and India) [1,2]. Trivalent Cr(III) and hexavalent Cr(VI) are the most common forms found in effluent water. Whereas trivalent chromium is a micronutrient (25–35 g/day) involved in the metabolism of lipids and carbohydrates [3,4], hexavalent chromium is exceedingly toxic, teratogenic, and mutagenic. Particularly concerning are its high solubility in water, mobility in detritus, and potential for bioaccumulation in living tissues. Due to these factors, hexavalent chromium has been the subject of numerous studies, especially its removal from effluent [5,6]. These studies have demonstrated that sorption is a highly effective and relatively simple technique for chromium removal from wastewater. In terms of this, magnetic heavy metals nanosorbents derived from inorganic compounds and polymers [7-9] are incredibly intriguing, because they could have been readily extracted from the mixture using an external magnetic field. The sorption investigation of hexavalent chromium in aqueous solutions on the magnetic aminofunctionalized polymer nanocomposite based on glycidyl methacrylate, m-PGMA revealed its highly selectivity and efficiency. [10,11]. The binding mechanism of hexavalent chromium ions onto m-PGMA was investigated using kinetic, equilibrium, and thermodynamic experiments as well as molecular modeling techniques (theoretical quantum-chemical calculations) [12-15]. It was observed that the process occurs in two phases. In the first phase, electrostatic interactions attract hexavalent chromium ions to the surface of the sorbent via the active sites (amino and APTMS groups). Cr(VI) is then converted to Cr(III) ions, which can coordinate with amino or hydroxyl groups on the surface of the sorbent [16]. The trivalent chromium ions that persist in the solution or on the surface of the sorbent are less hazardous than the initial hexavalent form. The application of m-PGMA sorbent enables the transformation of the toxic form of chromium into a less hazardous form, which is significant due to the possibility of sorbent regeneration and the subsequent processing of the solution following sorption.

AB  - A new magnetic amino-functionalized polymeric sorbent based on glycidyl methacrylate was synthesized and used in the separation of chromium Cr(VI) oxyanions sorption from aqueous solutions in a static batch system. The kinetic and isothermal parameters of the sorption process were determined. The experimental data were best fitted by a pseudo-second-order model with R2 = 0.994 and χ2 = 0.004. The sorption process of Cr(VI) removal by amino-functionalized sorbent was controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, followed closely by the Sips isotherm model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups that coated the magnetic nanoparticles. The calculations showed that Cr(VI) oxyanions (Cr2O72−, CrO42− and HCrO4−) bind to both sorption sites, with diethylenetriamine centers slightly favored. The X-ray photoelectron spectroscopy (XPS) spectra demonstrate that the chromium bound to the sorbent in the form of Cr(III), indicating that the Cr(VI) can be converted on the surface of the sorbent to a less harmful form Cr(III) due to the sorbent’s chemical composition.

AB  - Kinetic, equilibrium and thermodynamic of arsenate sorption onto magnetic polymer sorbent based on glycidyl methacrylate were investigated. The maximum sorption capacity of 0.59 mg/g was obtained. The experimental data were analyzed by seven kinetic models and eight isotherm models. Nonlinear regression method was used to fit the data to the kinetic and isotherm models. Thus, two error functions; coefficient of determination and Chi-square statistic test were applied to evaluate the sorption data. It was shown that arsenate sorption obeys the pseudo-second-order model with evident influence of pore and film diffusion. The Freundlich and all three-parameter isotherm models proved to be the best representatives of arsenate sorption. Thermodynamic studies implied endothermic and spontaneous process in nature.

AB  - Magnetic macroporous poly(glycidyl methacrylate-co-trimethylolpropane trimethacrylate) nanocomposite was synthesized by suspension copolymerization. The obtained nanocomposite was characterized by Fourier transform infrared spectroscopy (FT-IR), mercury porosimetry and scanning electron microscopy (SEM). Such magnetic nanocomposite was applied as sorbent for a dispersive solid-phase microextraction (DSPME) for aniline preconcentration from water samples. The parameters affecting the microextraction were optimized. The screening of DSPME parameters was determined using Plackett-Burman design (PBD). For the optimization of the most important factors Central Composite Design (CCD) was used. The analysis of the results showed that the pH value and temperature of desorption were the most significant factors.

AB  - Improving the affinity and selectivity of polymeric materials for sorbing ionic species, particularly
heavy metals that pose a high environmental risk, is crucial from an environmental standpoint.
Research on the mechanism of sorption can aid in selecting the optimal sorbent for a given
application. Sorption occurs as a result of various interactions. Sorption includes diffusion of ions
through solution (typically the quickest), diffusion of ions through the boundary layer surrounding
the sorbent surface, diffusion through the porous structure of the sorbent (intra-particle diffusion),
and binding to active sites on sorbent surfaces. Kinetic and equilibrium models explain the sorption
mechanism but not the nature of interactions, which is essential for predicting the selectivity and
efficiency of the sorbent based on particular ionic species. As a result, we were compelled to
approach the molecular level. Active sites on the surface of the magnetic aminofunctionalized
polymer, which are amino functional groups, are used to bind ions to the magnetic nanocomposite.
The sorption process can be viewed as the sum of ion-ligand unit interactions. Unit complex
formation and stability can be studied with statistical analysis and quantum chemical calculations.
The Cambridge database (CSD) improves the crystal structure of complex ion-ligand. Based on
binding energy, DFT (Density Functional Theory) predicts the stability of complex molecules (unit
ion-ligand interactions). To ensure an accurate calculation, it is essential to include all system
parameters, including sorbent structure, ligand properties, ligand charge under specific conditions,
ion forms and charges, and solvatation effects. In the early stages of research, defining the system's model lets researchers make theoretical predictions about the magnetic aminofunctionalized polymer sorbent's affinity and selectivity for certain ionic species.

AB  - The industrialization and urbanization expansion have increased the demand for precious and rare earth elements (REEs). In addition, environmental concerns regarding the toxic effects of heavy metals on living organisms imposed an urgent need for efficient methods for their removal from wastewaters and aqueous solutions. The most efficient technique for metal ions removal from wastewaters is adsorption due to its reversibility and high efficiency. Numerous adsorbents were mentioned as possible metal ions adsorbents in the literature. Chelating polymer ligands (CPLs) with adaptable surface chemistry, high affinity towards targeted metal ions, high capacity, fast kinetics, chemically stable, and reusable are especially attractive. This review is focused on methacrylatebased magnetic and non-magnetic porous sorbents. Special attention was devoted to amino-modified glycidyl methacrylate (GMA) copolymers. Main adsorption parameters, kinetic models, adsorption isotherms, thermodynamics of the adsorption process, as well as regeneration of the polymeric sorbents were discussed.

AB  - A core-shell amino-functionalized glycidyl methacrylate magnetic molecularly imprinted polymer (MIP) was synthesized by the suspension polymerization/surface imprinting method and characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), mercury porosimetry, nitrogen gas adsorption–desorption, and elemental analysis. This MIP was used as the sorbent in dispersive solid-phase microextraction (DSPME) of aniline from textile wastewater prior to high-performance liquid chromatography-mass spectrometry (HPLC-MS) measurements. Since aniline is toxic and a probable human carcinogen, its determination in water is of great significance. This is a challenging task because aniline is usually present at trace levels. The effects of different DSPME variables on the preconcentration efficiency have been studied by using the Plackett–Burman screening design of experiments (DoE) followed by response surface methodology optimization using the Box-Behnken design. Thus, DoE enabled the investigation of several variables simultaneously. Under optimized conditions, aniline was effectively and selectively separated by a small amount of the DSPME sorbent and detected in real textile wastewater samples. The method detection limit of 1 ng mL−1 was attained, with good method linearity and acceptable recovery and precision. The results showed that the studied MIP could be a reliable DSPME sorbent for efficiently analyzing trace aniline in real wastewater samples.

AB  - Over the decades, various sorbents have been used in the treatment of wastewater contaminated
with heavy metal ions, which seriously endanger the living world. Macroporous functional polymers show a high affinity for sorption of these ions, where sorption efficiency and selectivity directly depend on the nature of the functional groups of sorbent and metal ions. In this study, we performed a correlation of theoretical predictions and experimental data obtained by investigation of Cu2+, Co2+, Ni2+ and Cd2+ cations sorption under competitive and uncompetitive conditions from aqueous solutions on macroporous amino-functionalized sorbent poly(glycidyl methacrylate-coethylene glycol dimethacrylate), PGME-deta. Quantum-chemical calculations estimated the binding energies of metal ions to the active sites of the sorbent, on the model systems of individual
fragments, composed of metal ions and ligands, based on statistical analysis of data obtained from
crystal structures. By this theoretical approach, the high degree of correlation with experimental
data was observed for mono-component system.

abstract = "Over the decades, various sorbents have been used in the treatment of wastewater contaminated
with heavy metal ions, which seriously endanger the living world. Macroporous functional polymers show a high affinity for sorption of these ions, where sorption efficiency and selectivity directly depend on the nature of the functional groups of sorbent and metal ions. In this study, we performed a correlation of theoretical predictions and experimental data obtained by investigation of Cu2+, Co2+, Ni2+ and Cd2+ cations sorption under competitive and uncompetitive conditions from aqueous solutions on macroporous amino-functionalized sorbent poly(glycidyl methacrylate-coethylene glycol dimethacrylate), PGME-deta. Quantum-chemical calculations estimated the binding energies of metal ions to the active sites of the sorbent, on the model systems of individual
fragments, composed of metal ions and ligands, based on statistical analysis of data obtained from
crystal structures. By this theoretical approach, the high degree of correlation with experimental
data was observed for mono-component system., Decenijama se različiti sorbenti primenjuju za tretman otpadnih voda kontaminiranih jonima teških

AB  - Chelating copolymers show high efficiency in sorption of different ionic species in aqueous
solutions. The specific structure of chelating macroporous copolymers made by the porous
matrix and functional groups with the heteroatoms N, O, S and P; allows them to establish
various types of interactions with ions and molecules from the immediate surroundings.
Furthermore amino-functionalized macroporous copolymer of glycidyl methacrylate and
ethylene glycol dimethacrylate poli (GME) has a high capacity and good selectivity for the
precious and heavy metal ions over alkali and alkaline earth metals. In this study, aminofunctionalized
magnetic macroporous m-poli (GME)-deta was fully characterized in terms of its
structural properties using: FTIR, SEM/EDX and XRD analysis. The macroporous copolymer
was further used to investigate the sorption of pentavalent vanadium oxyanions from diluted
aqueous solutions (Ci = 25 ppm) in a batch system, at room temperature (298 K). The oxyanion
concentrations in a solution was determined by inductively coupled plasma atomic emission
spectroscopy (ICP-AES).The pseudo-first-order (PFO), pseudo-second-order (PSO), Elovich
and intra-particle diffusion (IPD) models were used to analyze the kinetic data.
The study has shown that sorption is rapid, i.e. the half-sorption time, t1/2 is approximately 1
minute. Initially, it has been the dominant sorption on the surface of the particles and the
process has been best described by the PSO model (which takes into account the binding
between sorbate and sorbent). The moment it has reached saturation of the sorbents surface
active sites, sorption rate decreases significantly because the sorption has been limited by the
rate of diffusion through the pores and kinetic has been controlled by the intraparticle diffusion
process. IPD kinetic model showed a good fit to the experimental data with R2 values > 0.95.

AB  - An amino‐functionalized magnetic macroporous copolymer of glycidyl methacrylate (GM) and ethylene glycol (E) dimethacrylate (m‐poly(GME)‐deta) was synthesized, fully characterized, and used to investigate the adsorption of vanadium (V) oxyanions from aqueous solutions (Ci = 0.5 mM) in a batch system at room temperature (298 K). Pseudo‐first‐order (PFO), pseudo‐second-order (PSO), Elovich, and intra‐particle diffusion (IPD) models were used to analyze the kinetic data. The study showed that sorption is rapid, i.e., the sorption half‐time is approximately one minute. Initially, the sorption process primarily involved surface sorbent particles, and it was best described by the PSO model. However, after saturation of the surface active sites is attained, the sorption rate decreases significantly because of limitations of the diffusion rate, which is then primarily controlled by the IPD process. The sorption process is favorable in the pH range of 3–6 due to the strong electrostatic interactions between the absorption centers of copolymer and vanadium (V) oxyanions. In the stated pH range, deta absorption centers with two and three protonated N atoms are in equilibrium as studied by quantum chemical modeling. Among V(V) species present in diluted aqueous media, the adsorption of H2VO4− ions dominates.

AB  - A new metal-chelating glycidyl methacrylate based macroporous copolymer with
ethylenediaminetetraacetic acid functions was tested as a potential Cu(II) and Pb(II) ions sorbent from aqueous solutions. The sorption was studied in non-competitive batch experiments, by varying initial pH and metal concentration, contact time and temperature. Pseudo-first and pseudo-second order model, as well as Bangham, intra-particle and liquid film diffusion models were used to determine the nature of sorption kinetics and the rate of limiting step. Equilibrium sorption data were analyzed with Langmuir, Freundlich, Temkin and Elovich isotherm models.

AB  - Statistical analysis of data from crystal structures, extracted from Cambridge Structural Database
(CSD) have shown that S and Se atoms in nonpolar environment display similar tendency
toward specified type interactions [1]. The most numerous are structures with C−H···Se and
C−H···S interactions (~80%), while structures with Se···Se and S···S interactions (~5%) are notably
less numerous (second type of interactions). When S or Se atoms is in a polar environment
(there is OH or NH grous in the vicinity), the distribution of certain types of interactions is slightly
different. Statistical analysis of S and Se interactions (criteria: d < 4.0 Å (for S) d < 4.5 Å (for Se),
Figure) showed the most numerous interactions with the H atom (in both cases about 47%), while
interactions involving C atoms (interactions with non-polar groups) are second in prevalence.
Interactions with non-polar C-H groups are slightly more numerous for Se (30%) than for S atom
(21%), while interactions with polar O-H and N-H groups are less numerous for Se (10% in total)
than in case of S atom (16% in total). Unexpectedly, the simultaneous interactions of X atom with
the S/Se atom and the polar OH/N-H group (H…X<3.5 Å) are only present in an amount of about
20%.
Results from docking study suggested that PBISe (Se compound) could be beter inhibitor of
iNOS (inducible nitric oxide synthase) than its S derivative (PBIT). All orientations of PBISe are
clustered at the same site (active site, Figure) leading to much better efficiency of this molecule
compared to PBIT, where three binding sites can be observed (Figure). This is in strong agreement
with experimental results pointing that PBISe kills melanoma cells >10−fold more effectively than
other iNOS inhibitors (PBIT).
AB  - Statistička analiza podataka dobijenih iz kristalnih struktura, ekstrahovanih iz Kembričke baze strukturnih podataka (eng. CSD), pokazala je da atomi S i Se u nepolarnom okruženju pokazuju

abstract = "Statistical analysis of data from crystal structures, extracted from Cambridge Structural Database
(CSD) have shown that S and Se atoms in nonpolar environment display similar tendency
toward specified type interactions [1]. The most numerous are structures with C−H···Se and
C−H···S interactions (~80%), while structures with Se···Se and S···S interactions (~5%) are notably
less numerous (second type of interactions). When S or Se atoms is in a polar environment
(there is OH or NH grous in the vicinity), the distribution of certain types of interactions is slightly
different. Statistical analysis of S and Se interactions (criteria: d < 4.0 Å (for S) d < 4.5 Å (for Se),
Figure) showed the most numerous interactions with the H atom (in both cases about 47%), while
interactions involving C atoms (interactions with non-polar groups) are second in prevalence.
Interactions with non-polar C-H groups are slightly more numerous for Se (30%) than for S atom
(21%), while interactions with polar O-H and N-H groups are less numerous for Se (10% in total)
than in case of S atom (16% in total). Unexpectedly, the simultaneous interactions of X atom with
the S/Se atom and the polar OH/N-H group (H…X<3.5 Å) are only present in an amount of about
20%.
Results from docking study suggested that PBISe (Se compound) could be beter inhibitor of
iNOS (inducible nitric oxide synthase) than its S derivative (PBIT). All orientations of PBISe are
clustered at the same site (active site, Figure) leading to much better efficiency of this molecule
compared to PBIT, where three binding sites can be observed (Figure). This is in strong agreement
with experimental results pointing that PBISe kills melanoma cells >10−fold more effectively than
other iNOS inhibitors (PBIT)., Statistička analiza podataka dobijenih iz kristalnih struktura, ekstrahovanih iz Kembričke baze strukturnih podataka (eng. CSD), pokazala je da atomi S i Se u nepolarnom okruženju pokazuju

AB  - 5HT1A receptor targeting drugs have been used as the treatment for the many neuropsychiatric
disorders, such as schizophrenia and depression. As a part of ongoing research, we designed series of
new compounds that share arylpiperazine common structural motif with the 5HT1A receptor ligand
aripiprazole. Receptor-ligand interactions were determined by the molecular docking simulations,
revealing the positive impact of the phenyl substitution in the arylpiperazine part of the molecules. Nine
selected compounds were synthesized in four reaction steps in high overall yields (59-73%). In vitro
pharmacological evaluation of the synthesized compounds revealed three compounds (5b, 6b and 6c)
with high 5HT1A binding affinity, comparable with aripiprazole (Ki 12.0, 4.8, 12.8, 5.6 nM,
respectively). Compounds from b series, 5b and 6b, possess 2-methoxyphenyl substituents, while 6c
possess 2,3-dichlorophenyl substituent in the arylpiperazine part of the molecule. The pharmacological
results are therefore in accordance with the molecular docking simulations thus proving the rational
design. Compounds 5c, 6b and 6c can be considered as the candidates for further evaluation as new,
potential antidepressants.

AB  - With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. Quantum-chemical methods may be applied in structural modeling, prediction, and characterization of such molecules and reactions. Sorption of metal ions (Cu2+, Cd2+, Co2+, and Ni2+) to triethylenetetramine-functionalized copolymer poly(GMA-co-EGDMA)-teta was successfully modeled by quantum chemical calculations, at the B3LYP//6–311++G**/lanl2dz level. Optimized structures of metal complexes were used for calculation of real binding energy of metal ion within the complex (ΔEr). Solvent and hydrolyzation effects were essential for obtaining the objective values. Solvent effect was included in ΔEr by using the total solvation energy for reaction of formation of tetaOH complex (ΔEs1, the first approach) or by using dehydration energy of free metal ion (ΔEs2, the second approach). Experimental results were confirmed in our theoretical analyses (using the second approach).

Solvent effect was included in ΔEr by using the total solvation energy for reaction of formation of tetaOH complex (ΔEs1, the first approach) or by using dehydration energy of free metal ion (ΔEs2, the second approach). Experimental results were confirmed in our theoretical analyses (using the second approach).",

AB  - Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantum-chemical models could be helpful for sorption process analyses. The sorption of Cu(II) ions by amino-functionalized chelating macroporous copolymers poly(GMA-co-EGDMA)-amine and sorption selectivity of the subject copolymers, ethylenediamine (en), diethylenetriamine (dien) and triethylenetetramine (trien), were successfully modelled by quantum chemical calculations. Considering the crystal structures from CSD and experimental conditions during the formation of metal complexes, the most frequent mononuclear complexes are those with the tetradentate teta ligand, while binuclear complexes are formed when the metal ion is in large excess. Although the en-copolymer was the most effective functionalized one, higher maximum sorption capacities (Qmax) were observed for the dien- and trien-copolymers, due to their abilities to form binuclear complexes. The enthalpy term has the greatest contribution to the total Gibbs energy change of reaction for the formation of mononuclear Cu(II) complexes (ΔGaq), while the solvation energy of the reaction has the greatest contribution in the formation of binuclear complexes. The results of the study indicate that small amines with the ability to form binuclear complex are the best choice for functionalization of the considered copolymer.
AB  - Квантнохемијско моделовање се показало као корисна алатка за разјашњавање процеса сорпције, као и за предвиђање структуре насталих производа те сорпције. Уз помоћ квантнохемијских прорачуна успешно су моделаовани процеси сорпције Cu(II) јона и селективност тих сорпција на амино-функционализованим хелатним кополимерима поли(глицидил-метакрилат-ко-етиленгликол-диметакрилат) (поли(GMA-ко- 
-ЕGDMA)) са различитим бројем амино група у свом саставу (етилен (-en), диетилентриамин (-dien) и триетилентетраамин (-trien) кополимери). Узимајући у обзир кристалне структуре из CSD и експерименталне услове приликом формирања комплекса са Cu(II) јоном, дошли смо до закључака да су најчешће структуре мононуклеарних комплекса са тетрадентатно везаним лигандима, али да се бинуклеарни комплекси јављају
када је јон металa у вишку у односу на кополимер. Без обзира на то што је кополимер са en-лигандима најефикасније функционализован, најбоља сорпција Cu(II) јона (Qmax) се, 
ипак одиграва на dien- и trien-кополимерима. Овакав резултат је последица боље способности dien и trien лиганада за грађење бинуклеарних комплекса са Cu(II) јонима. Највећи допринос укупној промени Гибсове енергије реакције грађења мононуклеарног Cu(II) комплекса (ΔGaq) потиче од енталпијског члана. Међутим, пресудну улогу на формирање бинуклеарних комплекса има солватациона енергија. Резултати наше студије показују да су краћи амини са могућношћу формирања бинуклеарних комплекса најбољи избор приликом функционализације разматраних кополимера за потребе сорпције Cu(II) јона.

AB  - Magnetite particles are widely used as sorbents for removal of heavy metal ions, organic dyes, drug delivery, cell labelling, magnetic resonance imaging, sensing, etc. [1,2]. Also, the functionalization of polymer by specific ligands enables customizing these composites for specific applications. Magnetic crosslinked macroporous copolymer of glycidyl methacrylate, GMA, and ethylene glycol dimethacrylate, EGDMA, mPGME was synthesized by suspension copolymerisation of GMA and EGDMA, in the presence of inert component (mixture of cyclohexanol and aliphatic alcohol) [3] and magnetite nanoparticles coated with (3-aminopropyl)trimethoxysilane (APTMS) as silanization agent. The sample was additionally functionalized with diethylene triamine mPGME-deta. Magnetic amino-functionalized copolymer was fully characterized in terms of its structural and magnetic properties using: FTIR analysis, SEM/EDX, XRD and SQUID magnetometry. Synthesized magnetic macroporous copolymer mPGME-deta was tested as sorbent of W(VI) and Cr(VI) oxyanions from diluted aqueous solutions (Ci=25 ppm) in a batch system, under uncompetitive conditions, at room temperature (T=25 °C). The oxyanions concentrations in solution after 60 min of sorption, were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The maximal experimental values of oxyanions sorption capacities (Qmax μmol/g) were compared with theoretically values determined by theoretical modeling, using quantum-chemical methods: Density Functional Theory (DFT), statistic analysis of the crystal structure extracted from the Cambridge Structural Database (CSD) and by implicit solvation model (SMD). It was found that the process is spontaneous and exothermic, and that the active sites of magnetic copolymer sorbent are amino groups (of diethylenetriamine and APTMS) which forms electrostatic interactions with oxianions W(VI) and Cr(VI).
